Reveal the main technical parameters of motor protector

Main technical parameters of motor protector:

(1) working voltage: ac three-phase 300 ~ 460V, 50Hz.

(2) overvoltage protection: 380 ~ 460V adjustable, delay about 0.5 ~ 5s adjustable.

(3) under voltage protection: adjustable for 300 ~ 380V, adjustable for delay of about 1 ~ 10s.

(4) phase fault and phase sequence protection: action time ≤0.2s.

(5) protective contact capacity: AC220V5A (resistibility).

(6) power consumption: < 3VA.

(7) the undervoltage and overpressure action characteristics of the protector are shown.Characteristic line 1 is single-phase overvoltage characteristic line;The characteristic line 2 is the characteristic line of two-phase over-under-voltage;Characteristic line 3 is the characteristic line of three-phase over-undervoltage.

(8) setting the overvoltage value of the protector -- setting the knob can set the maximum (upper limit) of the allowable operating voltage of the protected object.Undervoltage value -- the setting knob sets the minimum allowable operating voltage of the protected object.Overvoltage delay -- the time (s) when the operating voltage exceeds the set overvoltage value to reach the action of the protector.Undercalendering -- the time (s) when the operating voltage is lower than the set undervoltage to reach the action of the protector.
